OVEN-DOOR FOR C OOKlNG-STOVES.

SPECIFICATION forming part of Letters Fatent No. 434,893, dated August19, 1890 Application filed May 17, 1890. Serial No. 352,183. (No model.)

To all whom it may concern.-

'Be it known that I, WILLIAM H. Soorr, a citizen of the United States,residing in Fredonia, in the county of Chautauqua and State of New York,have invented certain new and usefulImprovements in Oven-Doors forCooking-Stoves, of which the followingis a specification.

The object of my invention is to produce a combined transparent andventilated ovendoor for cooking-stoves, all of which will be fully andclearly hereinafter described and claimed, reference being had to theaccompanying drawings, in which- Figure 1 is a front elevation of aportion or frame of an oven-door for acooking-stove, the

supplementary door, the glass, and the holding-frame being omitted. Fig.2 is a detached front elevation of the supplementary ovendoor. Fig. 3 isa detached front elevation of the glass-holding frame, and Fig. 4 isacross section through an oven-door complete in or about the line a b,Fig. 1.

In said drawings, 1 represents the frame of the oven-door. It ispreferably made of castiron, and is provided with the usual hingeportions 2 and knob 3, by which it is opened and closed when attached toa stove. It is also provided with the supplementary door-hinge portions4, by which the supplementary door is hinged thereto.

5 represents a small raised bend or molding surrounding the door, withinwhich the supplementary door fits when closed, substantially as shown inFig. 4.

In the door-fra1ne 1 is a depression or recess 6 surrounding the inneredge of the doorframe. (See Figs. 1 and 4.) XVithin this depressedportion 6 is a series of projecting lugs 7, each having a lower or stepportion 8. (See Figs. 1 and 4.) These lugs receive the glass 9, (shownin Fig. 4,) so as to hold it a short distance above the depressedportion 6 or the height of the steps 8. It will also be noticed that asthe glass fits within the lugs 7 it is slightly smaller than thesurrounding depression 6.

The supplementary door 10 is provided with the usual hinge portions 11and a knob 12 for opening and closing it when in its place on thesupplementary door-frame 1; but as these parts are all old and wellknown a further description here is not required.

Around near the edges of the supplementary door is a series of fineperforat1ons 13 to admit air through the supplementary door. The glass 9is secured in place by being placed within the inner edges of the lugs7, so as to rest on the steps 8, as before mentioned. The frame 14 isthen placed over 1t and secured by screws, which pass through the holes15 in the projecting portions 16 shown in Fig. 3, and into thescrew-holes 17 shown in Fig. 1, the depression 6 having cor respondingdepressions 18 to receive the portions 16. The frame 14 is provided withthe projecting corner-pieces 19, which leave the reduced portions 19.(See Fig. 3.) These reduced portions 19 leave openings around the framewhen it is in place, so that air will pass through the perforations 13and then around the edges of the frame 14 and glass 9 into the oven, inthe direction-of the arrows 1) shown in Fig. 4. The lugs 7 are madesufficiently high to allow the glass to be put in 7 5 and the frame 14to be firmly securedin place without breaking it. This constructionpermits a free circulation of air through the door, substantially ashereinbefore mentioned, and consequently within an oven to which it isattached, and it also provides a transparent portion in the side of themain door, through which articles within an oven may be seen Withoutopening the door or in any way dlsturbing the process of baking orcooking with- ,8 5 in it.

The object of the supplementary door is to protect the glass 9 andprevent it from being broken.

I claim as my invention- 1. The combination, in an oven-door forcooking-stoves, of a main frame portion, adepression 6 in the frameportion, a series of step-shaped lugs projecting therefrom, a sheet oftransparent material seated upon said lugs, 5 so as to be abovethebottom of the depression 6 and away from the sides thereof, aframepiece 14 for securing the transparent material in place, having theprojecting corners 19, and a supplementary door provided with 100 aseries of fine perforations, substantially as and for the purposesdescribed.

2. In an oven-door for cooking-stoves, the combination of a frameportion 1, provided with a depression 6, a series of step-shaped lugsprojecting from the depression 6,asheet of transparent material seatedupon the lugs and kept thereby away from the bottom of the depressionand from the sides thereof, and a frame for securing the transparentmaterial in place, provided with reduced sides 19, whereby an opening atthe sides and ends of the frame and glass and under it is provided forthe passage of air, substantially as described.

3. An oven-door for a cooking-stove, consisting of a main frame portionprovided with a depression having a series of step-shaped lugs, a sheetof transparent material seated upon said lugs and kept thereby away fromthe sides and bottom of the depression, a frame for holding thetransparent material in position, having depressions to form openingsaround its sides when in place, and a supplementary door for protectingthe transparent material, substantially as described.
